IIT TREC-9 - Entity Based Feedback with Fusion.

Abstract

For TREC-9, we focused on effectiveness in the web track. The key techniques we employed were information fusion, entity-based relevance feedback, Wordnet-based query parsing and a user interface designed to assist with web-based manual queries. Our initial results are positive. For the manual task, forty of fifty queries are over the median. In the adhoc, title-only task, thirty-four of fifty queries are over the median.
